Just so everyone knows, If you want to use an aftermarket MS3 poly rear mount, get one with a thin flange. I bought a torque solutions mount and it took extensive modification to be able to fit because the "fingers" or the flange on the TS mount were too thick. I had issues of the mount running into a bolt head on the bracket that mounts to the transmission.
I had to grind the bolt heads of both the bolt that goes through the mount and the one that bolts the bracket to the trans, and I also had to remove about .5" from one of the fingers of the flange. Unfortunately I forgot to take a pic of everything I had to modify to make it fit. but in that picture above you can see how much thicker the afermarket mount is compared to the stocker.
The best poly mount to use would be the JBR one linked before; http://www.jamesbaroneracing.com/sto...42_212_214_217
